UPDATE 06/02/13: Haswell just launched, and it looks like Intel did not change the manufacturing process of the thermal paste. Haswell still uses paste instead of solder between the IHS and die. The CPU in the video is an Ivy Bridge, but the delidding of Haswell still applies.

--------------------------------------------------------------------------------------------------------------

00:15 - temps before mod
02:24 - removing the IHS
10:02 - cleaning old stock thermal paste
12:56 - cleaning sealant glue
15:54 - applying new thermal paste
17:27 - installation into motherboard
20:27 - concluding temp results

Intro and background: With this generation of Intel processors, Intel decided to cut corners and use very cheap TIM (thermal interface material) between the bare CPU die and the top IHS (integrated heat spreader). Cheap TIM does not transfer heat away from the die well, that's why Ivy Bridge processor heat up very fast, especially when overclocking. With Sandy Bridge and earlier CPU's, Intel used fluxless soldering between the CPU die and the IHS, so they do not have this problem.

By taking the IHS off of Ivy Bridge processors to apply a better TIM, you can get a significant reduction in temperatures without needing additional cooling hardware. As a result from this simple mod, you may get a higher max overclock, more stable results, or reduction in fan noise for a quieter computer.

Do not try this with Sandy Bridge or earlier processor generations since they are soldered on, and much harder to remove the IHS. At the time of this video, here are all the Ivy Bridge models that this works on:

i7-3770K
i7-3770S
i7-3770
i5-3570K
i5-3570
i5-3550
i5-3470
i5-3450S
i5-3450

im sorry id rather buy better cooling, this is not worth the frucking
chance of ruining the cpu

Why is the cpu fan blowing to the GPU card?
Are you stupid?
Ever hear of a computer case and airflow?

you could have rma'd it but now you'll never be able to.
Probably just needed to reseat the heatsink...

wow impressive temp decrease! I have similar problem with one of the cores
going too hot, but in my laptop. Its i7 3630QM chip, I wonder if I can do
the same as you did with desktop cpu?

Do I need the heat spreader? I have a Core 2 Duo Penryn P9500 (mobile)
working without the grey heat spreader. Die->thermal paste->heatsink.

So, is it necessary to use the grey heat spreader for example a Core 2 Quad
Q6660? Or can I remove it and place the heatsink directly on top of the
die? Would that make it even better for the temperatures? I'm asking just
out of curiosity. ^^

I don't understand the critics here. The guy is showing us that if you're
careful, you CAN remove the heat spreader and NOT hurt the processor.
Furthermore, he's PROVING that Intel is putting poor TIM on their
processors. The shit that Intel puts on the chip runs hotter than the stuff
he used on the coolest running cores! He got a 5 degree drop in temps on
those coolest cores, not to mention fixing the disparity of the stock
temps. Now all the cores are running the same 5 degrees cooler than Intel
is giving us. This kid should be getting a medal from us, not criticism.

RMA? Since he proved to us Intel has a quality control problem, AND that
they're using cheap-ass TIM, why would you roll the dice with another
processor and maybe wind up with something worse? If you CAN do this, why
wouldn't you, especially since you'll wind up with something better than
the best quality processor that Intel can give you?

You guys criticizing him must be Intel worshipers, not just fan boys. He's
offended you by showing you your god is flawed.

So many people who doesn't own computer, or have some ancient pile of
trash... And this guy play with his cpu like that...
I'm so envy about some contries wealth...

Hey guys i have my i7 3770K run around 57° normal and 75-80° in use without
overcloking but with the basic intel fan. Is it normal or i need to change
the IHS too or just the fan ?

Thanks

this is stupid.who cares what the temp is as long as it keeps working.you
need to go out and get a girlfriend.
i mean you could have had sex instead in those 20 minutes you wasted in
film making.

look how flakey that stock thermal paste is :S makes me wanna replace mine
but i ahvent got the bottle to try this :P my temps arent bad atm if they
ever get too bad ill giev it a go

MX-2 is the thermal past i use on all my heatsinks

i did this it worked very well. thanks for the video friend :)

Good description, it really helps a lot. Thanks.

LOLOLOLOL you put the fan facing the wrong way you idiot the air is blowing
onto your gpu not your heat sink that's why..... It's stupid taking apart
a'$250 processor...
Barry Cooper (1 month ago)
Good video Bro. I always get the runt of the litter when it comes to
processors. Luckily my 3570k was a good one for once. 60 C @ 4.5 ghz. I
just needed 1.120 volts. Intel burn test puts the temps up to around 70 C.
Game play temps are all under 60 C. Thanks for taking the time to make this
video.

To have 1 core so far off it was a bad set job or did not have enough
thermal paste on the heatsink to the cpu.

You just ruined your intel cpu, what a waste anyways! An i7-4770k is half
price of the amd fx 8-core (yes unlocked) this processor does get cooled
easly and you dont have to destroy your cpu to make it cooler, i saw a core
at 38 degrees, which means it might be defect. Results in higher
temperature without a warning. Guess what! Im 14 and i know this stuff
because i actually think of a logic reason for things, dont take this as a
hate message because well... Its not my problem. Ps: the "glue" is not
glue, its an insulator.
